* The build system is currently miss-identifying GNU/kFreeBSD as FreeBSD.Sylvestre Ledru2013-07-011-2/+9
| | | | | | | | | | | | | | | | | This kind of simplification is sometimes useful, but in general it's not correct. As GNU/kFreeBSD is an hybrid system, for kernel-related issues we want to match the build definitions used for FreeBSD, whereas for userland-related issues we want to match the definitions used for other systems with Glibc. The current modification adjusts the build system so that they can be distinguished, and explicitly adds GNU/kFreeBSD to the build checks in which it belongs. Fixes bug #16444. Patch by Robert Millan in the context of Debian. llvm-svn: 185311

* [SystemZ] Add to --enable-targets=allUlrich Weigand2013-05-061-1/+1
| | | | | | | | | This patch finally enables the SystemZ target in the default build (with --enable-targets=all). Patch by Richard Sandiford. llvm-svn: 181209
* [SystemZ] Add configure bitsUlrich Weigand2013-05-061-2/+8
| | | | | | | | | | This patch wires up the SystemZ target in configure, so that it can now be built using --enable-targets=systemz. It is not yet included in the default build (--enable-targets=all); this will be done by a follow-up patch. Patch by Richard Sandiford. llvm-svn: 181208
* Allow host triple to be correctly overridden in CMake buildsTim Northover2013-05-041-1/+1
| | | | | | | | | | | The intended semantics mirror autoconf, where the user is able to specify a host triple, but if it's left to the build system then "config.guess" is invoked for the default. This also renames the LLVM_HOSTTRIPLE define to LLVM_HOST_TRIPLE to fit in with the style of the surrounding defines. llvm-svn: 181112

* configure: remove workaround for gcc's -Wno-maybe-uninitializedDmitri Gribenko2013-02-131-21/+11
| | | | | | | Since r174770 gcc version check is not needed because CXX_FLAG_CHECK implements the workaround itself. llvm-svn: 175080
* configure: when performing a compiler feature test for a -Wno-foo flag, attemptRichard Smith2013-02-081-13/+9
| | | | | | | | | to use -Wfoo instead of -Wno-foo. This works around a bug in some versions of gcc, where it will silently accept an unknown -Wno-foo option, but will generate an error for a compile which uses -Wno-foo if that compile also triggers any warnings. llvm-svn: 174770

* Enable AArch64 as a target built by default.Tim Northover2013-02-041-1/+1
| | | | llvm-svn: 174322
* Pass CPPFLAGS/CFLAGS/CXXFLAGS from the environment of configure toPatrik Hagglund2013-02-041-4/+11
| | | | | | | | | | | | | | | | | Makefile.config. This is implied at the bottom of the help text of configure (besides CC/CXX/LDFLAGS, already passed to Makefile.config). For backward compatibility, the values of CFLAGS and CXXFLAGS defaults to empty, overriding the default values provided by autoconf (for example, '-g -O2' when CC=gcc'). $(CPP) is not used by our makefiles. Therefore, the value of CPP is not passed to Makefile.config, despite beeing mentioned by 'configure --help'. llvm-svn: 174313

* Add -Wno-nested-anon-types to -pedantic builds of LLVM. This Clang warningRichard Smith2013-01-311-2/+6
| | | | | | | | | | | | | | | | | | | catches uses of an extremely minor and widely-available C++ extension (which every C++ compiler I could find supports, but EDG and Clang reject in strict mode). The diagnosed code pattern looks like this: struct X { union { struct { int a; int b; } S; }; }; llvm-svn: 174103
* Add AArch64 as an experimental target.Tim Northover2013-01-311-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for AArch64 (ARM's 64-bit architecture) to LLVM in the "experimental" category. Currently, it won't be built unless requested explicitly. This initial commit should have support for: + Assembly of all scalar (i.e. non-NEON, non-Crypto) instructions (except the late addition CRC instructions). + CodeGen features required for C++03 and C99. + Compilation for the "small" memory model: code+static data < 4GB. + Absolute and position-independent code. + GNU-style (i.e. "__thread") TLS. + Debugging information. The principal omission, currently, is performance tuning. This patch excludes the NEON support also reviewed due to an outbreak of batshit insanity in our legal department. That will be committed soon bringing the changes to precisely what has been approved. Further reviews would be gratefully received. llvm-svn: 174054

* Disable Uninitialized Use Warnings for Broken gcc VersionsDavid Greene2013-01-151-1/+13
| | | | | | | | | | | | Some versions of gcc accept unsupported -W flags and run just fine if there are no warnings, but die with an unsupported flag error if a warning is encountered. gcc 4.3 and gcc 4.4 both exhibit this behavior for -Wno-maybe-uninitialized. Therefore, if the flag check for -Wno-maybe-uninitialized succeeds, only use -Wno-maybe-uninitialized if we are using gcc version 4.7 or greater. Use -Wno-uninitialized otherwise. llvm-svn: 172543
* Disable -Wuninitialized for gccDavid Greene2013-01-091-6/+26
| | | | | | | | | | | | | | If the compiler is gcc, disable variants of -Wuninitialized depending on the gcc version. This gets a lot of false positive warnings out of the build. Generate a new configure for the gcc -Wno-uninitialized fix. Pick up -Wno-uninitialized from configure Add the option -Wno[-maybe]-uninitialized as determined by configure. llvm-svn: 172006
* Configure: if we compile with clang, check that it is not brokenDmitri Gribenko2013-01-091-2/+93
| | | | | | | | | | | | | | | Some linux distibutions (for example, Mageia 2, Fedora 17) ship Clang that is essentially broken for the end user. Clang can not find or compile libstdc++ headers. The issue is that our configure prefers clang over gcc, thus selecting a broken Clang when a working GCC is available. Now we detect this issue by compiling a simple program. If it does not compile, configure stops with an error suggesting the user to select a different compiler. llvm-svn: 171975
* Finally, fix the autoconf setup to allow for a missing clock_gettime;Chandler Carruth2013-01-051-4/+0
| | | | | | the source code should now be set up to handle this. llvm-svn: 171570
* Add time getters to the process interface for requesting the elapsedChandler Carruth2013-01-041-0/+104
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | wall time, user time, and system time since a process started. For walltime, we currently use TimeValue's interface and a global initializer to compute a close approximation of total process runtime. For user time, this adds support for an somewhat more precise timing mechanism -- clock_gettime with the CLOCK_PROCESS_CPUTIME_ID clock selected. For system time, we have to do a full getrusage call to extract the system time from the OS. This is expensive but unavoidable. In passing, clean up the implementation of the old APIs and fix some latent bugs in the Windows code. This might have manifested on Windows ARM systems or other systems with strange 64-bit integer behavior. The old API for this both user time and system time simultaneously from a single getrusage call. While this results in fewer system calls, it also results in a lower precision user time and if only user time is desired, it introduces a higher overhead. It may be worthwhile to switch some of the pass timers to not track system time and directly track user and wall time. The old API also tracked walltime in a confusing way -- it just set it to the current walltime rather than providing any measure of wall time since the process started the way buth user and system time are tracked. The new API is more consistent here. The plan is to eventually implement these methods for a *child* process by using the wait3(2) system call to populate an rusage struct representing the whole subprocess execution. That way, after waiting on a child process its stats will become accurate and cheap to query. llvm-svn: 171551

* Revert "Add --program-prefix support to build"Jordan Rose2012-09-261-10/+6
| | | | | | | | | | | | | The Apple buildbots are set up to pass --target to configure for both cross- and non-cross-compile builds, and the standard autoconf response to this is to set the program prefix to '<target>-'. Until we can figure out the proper way to handle this (don't pass --target? pass an explicit --program-prefix=""? don't auto-populate program_prefix with target_alias?) it's more important to keep the buildbots running. This reverts r164633 / ba48ceb1a3802e20e781ef04ea2573ffae2ac414. llvm-svn: 164651
